| |
Hi,
I have a working v1.3.80 which does IP Masquerading very neatly. As I am just experimenting, I simply do
ipfwadm -F -p masquerade
that is, the default Forwarding Firewall behaviour is to masquerade. The ipfwadm package is ipfwadm-2.0beta2.
But all the kernel versions 1.3.8[1-4] seem to have broken the masquerading code. I can open certain connections like telnet, http etc, but while ftp the data connections do not seem to be getting established. I can watch the connections with
ipfwadm -M -l -n
which lists the ports and I have never seen port 20 anytime in these kernel versions.
Has this something got to do with the recent reorganization of the masquerading code ? It looks so, because if I disable masquerading, IP forwarding as such is working cleanly.
I am trying to figure out what is going wrong. If any one out there can find further clues ...
